SCALDIIG-TANK' CONVEYER'.

Appiication inea August e, 1923. seriai no. gaseosa] E illinois, have invented new and useful Improvenieuts in Scalding-'lank Conveyers, of which the following is a specification.

The invention relates to scalding tanks and more particularly to means for convey ing carcasses in the tanks and from the re` cciving tothe discharge end.

It is an object of the invention to provide eiicient and positively acting means for conveying carcasses in the scalding vatso that uniform scalding of each carcass for the proper length of time is ensured.

A further object aims at providing means for conveying the carcasses in the tank'by a combined forward and .downward movement causing thereby a dipping of the car'- casses and uniform scalding thereof.

It is another object of the invention to provide a plurality of racks actuated by cranks of shafts and engaging with their teeth the floating carcasses whereby the latter are simultaneously advanced and dipped.

A still further obj ect consists in providing means for rendering the conveying means ineffective in case clogging of the scraping machine occurs vto which the scalded carcasses are delivered. y

It is also an object of the invention to provide certain features of construction and arrangement tending to improve a device of this particular character and to render the same highly efficient and reliable.

With these and other equally important objects in view, which will appear from the following description of the invention, the latter comprises the means described in the specification, particularly pointed out in the claims forming a part thereof, andillustrated in the accompanying drawing, in which- Fig. 1, is a diagrammatic side view of a tank to which my invention is applied, a portion of the tank being broken away to disclose interior construction.

Fig. 2, is a top plan view of the tank.

Referring to the drawing, 1 generally designates a vat or tank which comprises the bottom 2, the end walls 3 and the side walls 4. A shaft transversely extends through the vat and is journaled inbearings 6 provided therefor.

The shaft 5 is provided with a pair of cranks 'i' and 8, but if preferred the 1number of cranks may .be increased v0r .decreased as may be found expedient orjuseful. y

A shaft 9 equipped ywith CraDlSO and 11 n registry with the' aforementioned.cranks, transverselyeiitends through lthe vat 1hut at a distance from shaft 5. The side/wallsof the vat-areprovided with curved slots 12, the radii of curvature Aof vsaid Aslots 'being equal to the distance of thev shaft 5 and 9. The slots originate at the top of the side walls and extend far enough to maintain the shaft 9 in horizontal alignment with shaft 5. @pen bearings 13 are provided for shaft 9. y

The registering cranks 7, 10, and 8, 11 are connected by links 14: and 15 respectively whose lower sides vare formed asv racks. A pulley 1G is fast on the shaft 5 and power is transmitted thereto by a belt 17 from any suitable source of power. A sprocket wheel 18' is also fast on the shaft f 5 in registry with a sprocket wheel 19 keyed to the shaft 9. A chain belt 2O` is trained around the wheels 18, 19, so that rotation of theshaft 5 is transmitted to the shaft 9.

On the bottom of the vat a perforated plate 21 is provided which has secured thereto, a rope 22 or otherl lifting'means. The operation of the device is as follows:

Upon the delivery of carcasses such as hogs to the right end .(as viewed -in Fig. 1) and actuation of the shaft 5, rin clock4 wisevdirection, vthe racks 14:v and 15 are moved in a closed path but always in horizontal position. Thus the teeth of the racks will 'in the course of movement en-v gage the fioating hog carcasses and impart to them simultaneously a depressing and advancing movement toward the discharge end yof the vat. Thereby the carcasses are not only advanced'but also dipped, ensuring thereby a uniform sc'alding of the carcasses during their travel in thetank. Hot

water is always maintainedl in the tank to a level indicated at 23. From the discharge end of the tank, the carcasses are conveyed to a scraping machine (not shown). If

the latter does not function properly and conveying of carcassesvis to b e interrupted, y

then the plate 21 is raised by the ropes 22, and in this raising movement the 'shaft 9 is raised out of the tankthrough the slots 12, rendering the operation of the racks idle.

The drawing illustrates the invention more or less diagrammatieally. Various .changes andl modification may be resorted to Without departing from the principle of the invention. L'therefore, do lnot limit myself to the rdetails of construction and arrangementy as shown,v but include all.

changes constitutingv departures Within the scope and spirit of the invention-'as defined in the appended claims,

'I claim: K f

l. In anA apparatus of the kind speeiiied, a vat, a plurality of crank shafts transversely arranged in said vat, a rack conf neeting-theeranks olf said shafts, land means fork removing oneI of said'. shafts from the vat to render said rack idle.l

2. In an apparatus or' the kindspeoified, a vat, a plurality of crank shafts trans- ,Qd i V 1,537,543 e versely arranged in said vat, ka rack connecting the cranks of said shafts, one of said 'shafts hearing on the ends of slots provided in the vats,'and means for removingv said last named shaft from the vat Without varying the distance'- between said shafts. v 3. In'an apparatus of the kind specified, al vat, a v plurality of crank shafts trans'- verselyarranged in said vat, a rack connecting the cranks of said shafts, means for operatively connecting saidy shafts, and means for bodily removing yone of said shafts hutleaving the operative connections with the other shaft intact.

In' Witness whereof I aiiX my signature. l
